San Francisco Sheriff Ross Mirkarimi will let his undersheriff handle any disciplinary actions involving subordinates accused of domestic violence, but he will not give up oversight of his department’s domestic violence prevention programs, he wrote in a letter to Mayor Ed Lee. Mirkarimi is on probation after pleading guilty in March to misdemeanor false imprisonment for a New Year’s Eve argument in which he bruised his wife’s arm. His letter, sent earlier this week and obtained by The Chronicle, was in response to calls from Lee and District Attorney George Gascón to relinquish control over domestic violence programs at the Sheriff’s Department. The mayor and district attorney are exploring how to force the sheriff to do so, possibly through legislation.

The Planning Commission on Thursday reluctantly approved a proposed cap on the number of micro-apartments that can be built in the city. On a 6-1 vote, with Commissioner Michael Antonini opposed, the commissioners rejected the Planning Department staff recommendation to dump the 375-unit limit proposed by Supervisor Scott Wiener. Wiener suggested the cap after meeting with housing and tenant rights groups who were concerned that the 220-square-foot units would be marketed to young tech workers and displace much-needed family and low-income housing.

The deadline passed without a deal.

Academy of Art University, one of the largest landowners in San Francisco, has had “consistent and repeated violations” of city land-use rules, yet the city has repeatedly refused to fine the for-profit school, even after it missed two compliance deadlines, according to a confidential letter by City Attorney Dennis Herrera. The academy “is engaged in a game of obfuscation and delay,” and the city’s Planning Department has refused to issue notices of violation that could result in fines, despite those citations being ready to go, Herrera wrote in a confidential letter to planning Director John Rahaim obtained by The Chronicle.

A disability advocacy group sued Alameda County’s sheriff’s department Thursday claiming its main jail lacks the amenities necessary to properly care for inmates with disabilities. The lawsuit, filed in Alameda County Superior Court, claims that inmates with disabilities do not have proper access to toilets, showers or visiting areas. In addition, the lawsuit claims, some inmates with disabilities are discriminated against because they are housed in the jail’s infirmary, which is equivalent to them being placed in solitary confinement.

Board of Education President Norman Yee declared victory Thursday in one of the closest recent contests for a seat on the Board of Supervisors, but the second-place finisher has not ruled out requesting a recount.

The district includes the neighborhoods west of Twin Peaks.

Lewis Van Blois of Oakland filed the lawsuit Thursday in Alameda County Superior Court on behalf of victim Peter Cukor’s wife, Andrea Cukor, and their two adult sons, Christopher and Alexander. On the night of Feb. 18, Cukor and his wife arrived home to find a 23-year-old man, Daniel DeWitt, near their garage and asking to see a woman named Zoey. The couple said they did not know Zoey and told DeWitt to leave.
